mFI mPower Pro: how to set relays ON or OFF

[Number8]

For those willing to control relays of mFI mPowerPro (6 outlets), I thought it might be interesting to have in one place everything that needs to be done in order to have Domoticz able to trigger the relays. Everything has been done using a Windows PC
Step 1: set a static IP address. There is no provision in the Web GUI to do that.
• Get the unit directly connected to your PC with an Ethernet cable.
• Set the PC Ethernet static address to 192.168.1.10
• WinSCP to mPowerPro using 192.168.1.20. User = ubnt, password = ubnt
• Edit /tmp/sytem.cfg, and modify it according the following instructions

Code: Select all

dhcpc.2.status=disabled
netconf.2.ip=staticIPAddress
netconf.2.netmask=netmask
route.1.status=enabled

Add the following lines
route.1.devname=eth1
route.1.gateway=(Put your gateway address here)
route.1.ip=0.0.0.0
route.1.netmask=0

• Quit
• Log to the unit using SSH
• Hit Save, then Reboot. The unit shall have now a definitive static address. Connect mPowerPro and the PC to the regular network. Set the PC network interface to what it was before this step.

Step 2: update mPowerPro to the latest firmware as per these instructions: https://help.ubnt.com/hc/en-us/articles ... s-manually. I did it using SSH.

Step 3 (optional): you may wish to get the relays OFF when the unit boots (default behavior is ON).
• Log to the unit using WinSCP
• Edit /etc/persistent/vpower_cfg
• Add the following lines (if you wish to have all relays off at boot time)

Code: Select all

vpower.1.relay=off
vpower.2.relay=off
vpower.3.relay=off
vpower.4.relay=off
vpower.5.relay=off
vpower.6.relay=off

• Save it, then enter cfgmtd -w -p /etc
Please bear in mind that at next boot time those 6 lines will be deleted, but the unit will behave as expected until the configuration of the unit is modified with the Web GUI.

Step 4: automate SSH login from Raspberry to mPowerPro.
Domoticz runs the script under root, so it is critical to get the public/private key created under root.
• Log to Raspberry using your preferred software (I’m using putty).
• Go to SU (you may need to activate this account the first time. Instructions are easily found on the Web)

Code: Select all

ssh-keygen –t rsa <return>
Hit 3 times return

• Private and public keys are in /root/.ssh. Copy id_rsa.pub to mPowerPro /var/etc/persistent/.ssh/authorized_keys
This is it, Domoticz will be able to send a script to mPowerPro without being asked a password.

Step 5: it is time to write the script. Mine stored in /home/pi/domoticz/scripts

Code: Select all

#! /bin/bash
ssh ubnt@mPowerProIPAddress "\$(echo $2 > /proc/power/relay$1)"

First parameter sets the relay to be controlled (1 to 6), the second parameter (0 or 1) sets the relay OFF or ON.

Step 6: Create a virtual switch, then edit the ON and OFF action as per following for relay 1:
• ON - script:///home/pi/domoticz/scripts/switchOnOff.sh 1 1
• OFF - script:///home/pi/domoticz/scripts/switchOnOff.sh 1 0

Thanks for this. FYI to anyone else trying this, I still use the mFi controller so I needed to use admin@ for the script.

Did you look into reading values from mFi gear?

To get it running every 5', this line is added in the crontab

Code: Select all

*/5 * * * * ( sleep 30 ; /home/pi/domoticz/scripts/mFIGetValues.sh)

Sleep 30 is because I don't want this script to be fired at the same time as other scripts

Hello!

I am reading this post for over 2 days and i have a few questions,
Situation: Domoticz on synology nas but can't reach the script location so installed another domiticz on my raspberry pi.
I have a MFI Mpower (password and username NOT default).

- in step 1 u disable the auto dhcp is that necessary when i have a fixed IP set in my router ?
- in step 4 u create a ssh key, i did create it and tried to upload it to the mfi but i can't find the location so i'm unable to upload them.
- in step 5 u place the script i did the same but as you will aspect no result.

can u please help me with this one ?
or is somebody working on a package the contains the solution already.

kind gerards!

Hi jschatorje,
Sorry, I took a few days off I could'nt answer to you right away

in step 1 u disable the auto dhcp is that necessary when i have a fixed IP set in my router ?

You may use your solution it will lead to the same result, ie contacting the mFI with a static IP address.

in step 4 u create a ssh key, i did create it and tried to upload it to the mfi but i can't find the location so i'm unable to upload them

you may use this path with is the same. You may have to create the .ssh directory I don't recall whether it was there or not

Code: Select all

/etc/persistent/.ssh

Something I may have overlooked. The first time you have to initiate a manual SSH connection to the mFI gear in order to get the connection authentified. To do so, log the Raspberry with your ssh client and issue the following commands:

Code: Select all

su
ssh ubnt@mFIIPAddress

A windows will popup, say yes.
Then you may check the execution of the script manually. If it succeeds the final step is to get the script registered in the crontab.

[ayasystems]

If you have a problems to connect try this:

(need to install sshpass)

Code: Select all

sshpass -p 'ubnt' ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o KexAlgorithms=+diffie-hellman-group1-sha1 [email protected]

so the script must be adapted:

Code: Select all

#! /bin/bash
sshpass -p 'ubnt' ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o KexAlgorithms=+diffie-hellman-group1-sha1 [email protected] "\$(echo $2 > /proc/power/relay$1)"
